/**
* A representation of color profile data for device independent and
* device dependent color spaces based on the International Color
* Consortium Specification ICC.1:2001-12, File Format for Color Profiles,
* (see <A href="http://www.color.org"> http://www.color.org).
* <p>
* An ICC_ColorSpace object can be constructed from an appropriate
* ICC_Profile.
* Typically, an ICC_ColorSpace would be associated with an ICC
* Profile which is either an input, display, or output profile (see
* the ICC specification). There are also device link, abstract,
* color space conversion, and named color profiles. These are less
* useful for tagging a color or image, but are useful for other
* purposes (in particular device link profiles can provide improved
* performance for converting from one device's color space to
* another's).
* <p>
* ICC Profiles represent transformations from the color space of
* the profile (e.g. a monitor) to a Profile Connection Space (PCS).
* Profiles of interest for tagging images or colors have a PCS
* which is one of the two specific device independent
* spaces (one CIEXYZ space and one CIELab space) defined in the
* ICC Profile Format Specification. Most profiles of interest
* either have invertible transformations or explicitly specify
* transformations going both directions.
* @see ICC_ColorSpace
